After a 4-8 season in 2008, Texas A&M is in rebuilding mode under second-year head coach Mike Sherman. The spring showed that the Aggies are in a better position with a host of young returning players and a better understanding of both the offense and defense.

First, we'll take a look at the top impact players on the Aggie roster heading into fall training camp. These aren't necessarily the best players, but rather the players that could make the biggest impact in a successful 2009 campaign for the Aggies.
